Abstract
A gas venting system with an electrically operated exhaust fan used in an enclosed garage to expel unwanted gases, especially carbon monoxide, to outside the garage and away from an attached residence. In a garage with a door opener with an automatically operative light fixture, power to operate the electrically operative fan is supplied from the connected light fixture, via an interconnected relay, during the normal preset time interval the door opener's light is operating.
Claims
exact text as granted — not AI-modifiedWhat we claim as my invention is:
1. A garage gas ventilation system comprising: an enclosed garage having garage walls and a garage door providing a gas confining space, said garage door adapted to operate and permit a vehicle to enter or exit from the enclosed garage; an electrically operative garage door opener having a light in said garage, said opener and opener light being connected to operate in response to the operation of the garage door; an electrically operated vent assembly adapted to be mounted on the garage and to provide a gaseous conduit to outside of the garage, said assembly including an electrically operated fan to exhaust gas from the garage; means for triggering the operation of said fan responsive to the operation of the light on said electrically operated garage door opener whereby said operative fan exhausts the garage's internal gas from the garage to the outside.
2. The system as claimed in claim 1, wherein said garage door opener's light is supplied electrical power for a preset time interval; and said means for triggering the operation of said fan is operatively connected to said light fixture to trigger the operation of the fan during the same preset interval electricity is supplied to the light.
3. The system as claimed in claim 2, wherein said means for triggering the operation of said fan is operative connected to the light fixture by an electrically operated relay interconnecting the fan to the light.
4. The system as claimed in claim 3, wherein said electrically operated vent assembly has movable louvers which open to outside the garage when said fan is operative to exhaust gas from the garage.
5. The apparatus as claimed in claim 4, also including an outside air intake into the garage mounted on the garage.
6. The apparatus as claimed in claim 1, wherein said enclosed garage is attached to a personal residence by an interconnecting door.Join the waitlist — get patent alerts
